He was the dominant three-year-old of his generation in Europe in the spring and summer of 1961, winning the Poule d'Essai des Poulains, Prix du Jockey Club and the King George VI and Queen Elizabeth Stakes.
[2] In July, Right Royal was sent to England to contest the King George VI and Queen Elizabeth Stakes in which he was matched against the 1960 Epsom Derby winner St. Paddy.
Ridden by Roger Poincelet, he started at odds of 6/4 with St Paddy being made the 4/5 favourite in a race run on rain-softened turf.
Right Royal tracked St Paddy until the final furlong when he was moved to the outside and easily accelerated past the English champion, winning by three lengths.
He sired the 1969 Irish Derby winner Prince Regent and Salvo, who won the Hardwicke Stakes and the Grosser Preis von Baden and finished second in both the King George and the Arc.
